It was a chaotic night in Austin as Interactive and Film closed, and the Music portion officially began at the YouTube Welcome party featuring a great lineup of artists including Das Racist.
The biggest news of the night was the surprise performance by Foo Fighters at Stubb's. With barely an hour's notice after they screened their new documentary, they took the stage and delivered an electrifying performance to a capacity crowd.
Elsewhere, Beach Fossils, Surfer Blood, Boxer Rebellion and Psychic TV rocked Austin and ushered in the start of music lover's heaven.
One other big development: Kanye West has confirmed at the Fader Fort for Saturday, with a rumored appearance by Bon Iver on the books.
